Specification of Letters Patent.

Patented June 26, 1906 Application filed February 1, 1905. Serial No.243,659.

To all whom it may concern.-

Be it known that I, WILLIAM CLINE, a citizen of the United States,residing at Lancaster, in the county of Lancaster and State ofPennsylvania, have invented certain new and useful Improvements in Aparatus for Purifying Smoke, of which the fo lowing is a specification.

My invention has relation to an apparatus whereby the heavy and thickproducts of combustion may be removed from smoke prior to its entranceto and c exit from the stack proper, and in such connection theinvention contemplates an arrangement and combination of arts wherebythe washing of the smoke and t e precipitation of the heavier andthicker products of combustion are efficiently performed withoutinterfering with the draft.

Heretofore manufacturers and others who desired to use soft coal orsimilar fuel have been restricted in or deterred from its use by reasonof the heavy clouds of smoke issuing from the stack after each firing ofthe furnace or furnaces, said heavy clouds of smoke being considered bythe authorities in many municipalities a public nuisance. Some attemptsto palliate or remove this defect of soft coal as a fuel have beendevised, such attempts being directed along two main linesto wit,'first,the more complete consum tion of the fuel in the furnace, flue, or stacor, second, the screening and washing of the smoke in either thesmoke-stack or an auxiliary flue or condensing chamber leading from theflue of the furnace to the stack. In the first of these attempts thereor anization of the furnace or the change in plan of the stack andflues was necessary, an

such reorganization or change has been so expensive as to practicallyprevent the use of such means for the purposes required. In the secondof these attem ts the introduction of screen-plates or be e-plates inthe stack or flue-chamber, as well as the introduction of liquids insaid stack and chamber, have together served to increase rather thandecrease the nuisance, inasmuch as a serious diminution of the draftresults from the introduction of such impediments as plates or screensor spraying-nozzles in the flue or stack.

The object of my present invention is to provide a simple and practicaldevice or apparatus whereby the heavy or thick partir of the smoke areremoved prior to the exit the smoke from the stack and without pairingthe draft, but, on the contrary, m urably increasing said draft tothereby sec a more complete consumption of the prior to the exit of theproducts of coml tion from the stack.

The nature and scope of my invention. be more fully understood from thefollov description, taken in connection with the com anying drawings,forming part he] inw 'ch Figure 1 is a view illustrating diagramr icallyan apparatus for carrying out m vention, the stack bein illustrated inver section, whereas the ue and flue-cha1 are illustrated in transversesection. is an enlarged plan view, artly se illustrating 1n detail oneof the spraye Referring to the drawings, a repres flue from a furnace orheater, and sents the stack or chimney.

BEST AVAlLABLE COPY ite each perforation is arranged a stud ofpreferably conical shape, the apex of re cone approaching theperforation 6 as clearly illustrated in Fig. 2. The jet of liq- 1l(lissuing from each perforation e is pound- :d or pulverized into a finemist or spray, he series of jets thus forming a more or less hick veilof vapor traveling toward the ack end of the flue-chamber d. This veilvapor effectually separates the thicker and- :avier particles of theproducts of comistion passing through the chamber from .o fire-gases anddeposits said particles in .e base of the chamber (1. The minute par-:les of liquid issuing from the sprayer-pipe will in passing into thesmoke become :hly heated and will expand toward the tCk end of thechamber d, thus accelerating e passage of the products of combustion thestack, as well as cleansing the smoke an the heavy and thick impurities.As istrated in Fig. 1, two sprayer-pipes e are wided-one some distancebeyond the inend of the chamberd and the other at said at end, butbeyond the outlet from flue a. lesired, however, but one pipe e may bed, or more than two may be required, acding to circumstances; At thebase of amber d is a pipe 9, conveying exhaustroin the engine or othersource to the :r c'l. While not necessary, the iniion of thisexhaust-steam will be desirable to prevent contraction or isat'ion ofthe smoke which might perake place if the liquid introduced ,h sprayerse were cold. In Fig. 2 the e of the sprayer-pipes e are each retblycarried at one end of a hook-shaped et e. The other end of this brackete ilar, as at 6 to surround the pipe e we adjustable longitudinallyalong the A set-screw 6 serves to lock the 1d e to the pipe e. asexplained, the operation of the as follows: A liquid, preferably wa-:ced through pipe e to one or more pipes e and issues from said pipesI2LPOI'lZ8d or atomized form. The din of the travel of this vapor isboth up vn transversely across the chamber las longitudinally toward itsstack 1e veil or veils of vapor in chamber iitate the heavy and thickparticles moke, and the liquid collecting in the f the chamber (1 andcarrying these es is drained off by pipe d into the i tankf .e pipe emay be supplied with liquid unressure from any suitable source. Howinlarge plants where great'quantities ,uid are to be supplied to thesprayers it be found necessary in order to operate device with economyto reutilize the spentfiiquid drained off from the chamber (1. Thisreutilization of the water or liquid E forms a feature of my r sentinvention.

1k; clearly illustrated in Fig. 1, the vat or tank f is but one of aseries of communicating vats f f f The vat f has a stand-pipe 72.,forming an outlet for water or liquid at the bottom of tank or vat finto the next tank or vat f. This tank f has a similar stand-pipe h,forming an outlet for the liquid from the base of tank f to the tank fand a pipe 7L2, traversing the tank f 2 and terminating near its bottom,is the supply-pipe to a pump 2), which forces the liquid to the pipe e,which supplies the sprayers. The waste liquid flowing to the first tankf will rise in said tank with a thick scum h of the smoke impuritiescollecting on its surface and with the bottom of the tank filled byrelatively pure liquid. This relatively pure liquid ascends thestandpipe h and overflows into the tank f, in which it ascends with ascum 7L5 of impurities on its upper surface, and the still less impurewater overflows through into the next tank f The purer portion of liquidin the base of tank f 2 is then pumped to the sprayers for reutilizationin the chamber (1. Besides being more economical with regard to waste ofliquid, this reutilization of the liquid insures the delivery to thesprayers e of a heated body of li uid, and the heated liquid whensprayed will vaporize more quickly and combine more completely with thegases of combustion than if the sprayed liquid were cold. A pi e msupplies fresh liquid to any one of t e three tanks f f, or f in seriesto compensate for the waste due to the evaporation of the liquid eitherin chamber (1 or in the tanks.

Having thus described the nature and objects of my invention, what Iclaim as new, and desire to secure by Letters Patent, is
